IMPROVEMENT IN SWINGS.

Specification forming part of Letters Patent No. 115,825, dated June 13,1h71.

To all whom 'it may concern: Y

Be it known that I, JESSE A. CEANDALL, of Brooklyn, in the conntyofKings and Sta-te ot' N ew York, have invented a new and ImprovedChildrens Swing; and I do hereby declare that the following is a full,clear, and exact description thereof, which will enable others skilledin the art to make and use the same, reference being had to theaceornpan ying drawing forming part ot this specification.

Figure 1 represents a front View of my improved swin g. Fi g. 2is a side View of the'saine.

Similar letters of reference indicate vcorrespondin g parts.

This invention relates to a new mechanism which 1s applied to a swingfor imparting inotion to it andconsists in the use of elbow-1everspivoted to the sides ofthe swing, and diagonal ropes connected therewithand with the supporting-frame, so that by oscillating the levers theropes will be pulled to carry the swing forward.

A in the drawing represents the body of the swing, carrying a. seat ofsuitable kind, and suspended by ropes B B from the supportingframe orlintel C. To each sideof the swing A is pivoted, at a., an elbow-lever,l), whose upper arm constitutes a handle, I), while its horizontal arm c1s, by a diagonal rope, d, connected with the frame or lintel C. Thelever projects backward from its pivot, while the rope el extendsforward from the lever. When the swing is carried back the levers D l)are by the hands swung back, and thereby pull on the ropes d, which willcarry the swing forward with increased power. The swing is thus readilykept in motion.

The levers D, instead of being Lshaped, as shown, In ay as well b`ecurved or of other equivalent form, and may, instead of projectingbackward, extend forward, to be used when the swing has been carriedforward. In such case'the ropes d would extend backward from the levers.

I ain aware of the Shzeft'er swing,patented in 1867, and desire todisclaim, as any part of my invention, all that is described or shown byhim. 1

' Having thus described my invention, I claim as 'new and desire tosecure by Letters Patent- The elbow-lever b c D and swing-body A',combined with flexible cords B B and d d', arranged as and for thepurpose specified.
